Extend the life of your blowout by using a coated fabric shower cap (Benefit Bathina Shower Cap, $16) instead of a plastic one, which can make you sweat and create frizz. Before bed, pile your hair on top of your head and secure with a nonmetal elastic band (
Goody Ouchless elastic bands, $2/pack) to boost volume without causing dents. Lastly, revive sections that have gone flat with a styling lotion (
Bumble and Bumble Prep, $17) then blast with heat from a dryer.
